"The wxWidgets toolkit contains powerful, cross-platform tools for graphical user interface development. In addition to its native C++, several languages offer wrappers for use with the toolkit. Learn how to use the wxWidgets toolkit to create elegant and highly useful GUIs in your language of choice."

Huh? What about Qt? What disqualifies it? I write *true* cross-platform code with Qt professionally. It's what I do. Currently I'm porting a client's ancient MFC-4.0 code to WinXP, Mac OSX, Linux and multiple flavors of Unix. On each platform the appropriate *native* low level libraries are used. Heck, in 4.2 dialog buttons even get reordered according to platform!

How is this not "true cross-platform"?

While you may have a personal dislike for Qt, and find it doesn't meet your project's needs, you cannot argue that it is not true cross-platform. Because it is.
